Preparation has begun on a standard guide that will provide a
set of criteria that can be used by architects, engineers, and
builders to specify the desired acoustical quality of multi-family
dwellings.

A task group of ASTM Subcommittee E33.04 on Application of Acoustical
Materials and Systems has been formed to develop the guide, providing
graduated criteria for airborne and impact (footfall) noise. Later,
the scope may be expanded to include additional criteria for other
noise sources commonly found in multi-family dwellings, such as
plumbing fixtures and pipes, vent fans, etc.

The task group will research existing performance requirements
and eventually develop classes of construction to allow consumers
and builders choices for acoustical privacy.
